Summary: Acute kidney injury (AKI) is a common and devastating condition with no effective pharmacological treatment. Toll-like receptor 4 (TLR4) and its ligands play a crucial role in the pathogenesis of AKI by mediating inflammatory responses. Excessive activation of TLR4 can lead to chronic inflammation. This review discusses the role of TLR4 in ischemic/reperfusion-induced AKI and sepsis-associated AKI, as well as its potential signaling patterns in kidney injury.

Summary: This study aimed to investigate whether a novel Toll-like receptor 4 agonist could attenuate acute kidney injury induced by ischemia-reperfusion injury. The results showed that pretreatment with the agonist improved kidney function, reduced renal tissue injury and apoptosis. The findings suggest that the agonist can provide protection against ischemia-reperfusion injury-induced acute kidney injury.

Summary: This study investigated the relationship between the gut microbiome and intestinal ischemia/reperfusion (I/R) injury. It found that Lactobacillus murinus can alleviate intestinal I/R injury in mice through macrophages, and this effect may be achieved by promoting the release of IL-10 from macrophages through TLR2. This study revealed a novel mechanism of intestinal I/R injury and provided a new therapeutic strategy for clinical practice.

Summary: Stroke is caused by ruptured or blocked cerebral blood vessels and subsequent disruption of brain blood circulation, resulting in rapid neurological deficits. The majority of stroke cases are ischemic strokes. Current treatments for ischemic stroke, such as t-PA thrombolytic therapy and surgical thrombectomy, can paradoxically lead to ischemia-reperfusion injury, exacerbating brain damage. Minocycline, a semi-synthetic tetracycline antibiotic, has demonstrated a wide range of neuroprotective effects independent of its antibacterial activity. In this article, we summarize the mechanisms underlying the protective effects of minocycline against cerebral ischemia-reperfusion injury, including modulation of oxidative stress, inflammatory response, excitotoxicity, programmed cell death, and blood-brain barrier injury. We also discuss the role of minocycline in alleviating stroke-related complications, providing a theoretical basis for its clinical application in cerebral ischemia-reperfusion injury.

Summary: Panax notoginseng derived exosome-like nanoparticles (PDN) are nanoparticles extracted from Panax notoginseng that can promote the repair and treatment of neurological damage. PDNs can enter the brain, reduce cerebral infarction, improve behavioral outcomes, and maintain the integrity of the blood-brain barrier. The study also found that PDNs attenuate inflammation by altering microglia phenotype, thereby alleviating cerebral ischemia/reperfusion injury.

Summary: TLR4 signaling in neurons plays a crucial role in neuronal death and neuroinflammatory responses following brain ischemia. Deletion of TLR4 reduces neuronal death and intracellular Ca2+ influx induced by oxygen and glucose deprivation or lipopolysaccharide treatment. TLR4 interacts with NMDAR2B and affects the interaction between nNOS and PSD-95, contributing to ischemic injury.

Summary: The study found that Nec-1 may reduce myocardial cell death and maintain myocardial architectural integrity, thus inhibiting the reactive fibrosis process in rats during myocardial ischemia/late reperfusion. Administration of Nec-1 at the onset of reperfusion significantly reduced the release of creatine kinase and downregulated autophagy within 24 hours after reperfusion, with a significantly positive correlation between them.

Summary: Mycophenolate mofetil (MMF) treatment significantly alleviates hepatic ischemia/reperfusion (I/R) injury by reducing serum biomarker levels and tissue necrosis. The protective effects of MMF are achieved through inhibiting TLR4 activation and NF-kappa B pathway, decreasing inflammatory cytokine expression, inhibiting hepatocyte apoptosis, and inducing autophagy.

Summary: The onset of cardiogenic cerebral embolism is sudden and dangerous, with factors such as severity of neurological impairment, types and severity of combined heart diseases, establishment of cerebral collateral circulation, treatments, components of emboli causing cardiogenic cerebral embolism, existence and control of other system complications, distribution and expression of inflammatory immune cells and molecules, and epigenetic changes related to disease prognosis all influencing patient outcomes. Emphasis should be placed on clinical settings, emboli pathological profile, and epigenetic changes in the prevention and treatment of cardiogenic cerebral embolism to improve outcomes and reduce recurrence.

Summary: This study investigated the changes in immune cell composition in the peripheral blood of patients with acute ischemic stroke (AIS) based on their age groups. The results showed that the proportions of certain immune cells differed among the age groups, with a decrease in certain cells as age increased. These differences may have implications for clinical outcomes and suggest the need for customized treatment for AIS in different age groups.

Summary: Gallstone disease is a common digestive system pathology with a 10-20% incidence rate among adults. Cholecystectomy is the main treatment, but it can cause physical pain and greatly impact a patient's quality of life. Clinical research suggests that cholelithiasis is closely related to age, gender, body mass index, and other physical characteristics, as well as obesity, diabetes, non-alcoholic fatty liver, and other diseases.

Summary: This study used high-resolution magnetic resonance imaging to investigate the characteristics of patients with moyamoya disease and anterior intracerebral hemorrhage. The results showed that the length of lenticulostriate arteries was shorter and the lumen area of the terminal internal carotid artery was larger in the hemorrhagic group compared to the ischemic group and asymptomatic group. Multivariate analysis revealed that these features were significantly associated with anterior intracerebral hemorrhage. Additionally, the coexistence of reduced lenticulostriate arteries and relatively preserved lumen area of the terminal internal carotid artery may serve as a potential predictor of anterior intracerebral hemorrhage in moyamoya disease patients.

Summary: This study explored the effect of post-stroke exercise conditioning on brain injury and gluconeogenesis regulation. The results showed that exercise reduced brain infarct volumes, cell death, and neurological deficits after stroke. This neuroprotection was associated with the activation of the PI3K/AKT/FoxO1 signaling pathway and inhibition of gluconeogenesis.

Summary: The COVID-19 pandemic has had significant consequences for patients with cerebrovascular disorders requiring interventions. The study found an increase in cerebrovascular accidents, a decrease in elective carotid endarterectomies, and an increase in carotid stenting during the pandemic. Patients from ethnic and racial minorities were disproportionately affected, and delayed care and prolonged operative times resulted in worse outcomes.
